Welcome, lusa. That is a gorgeous drawing. While I can't help you on local pricing, I did want to comment on this:
at this price tag I guess I will not be able to afford a pool.
It's possible that while you can't afford THAT pool, if your motivation to have a pool for the relaxation and enjoyment of life, there are other options, depending on how much you want it
I felt the same way a few years ago after being told at my old house we'd have to tear down the garage and 2 hundred year oaks to build. I had sticker shock and was concerned that the money it would take was not worth it in relation to my particular house, which was big, old, with wicked stairs and not a place I thought we'd be able to age in place.
Solution? I went out and found a house with the setting and a pool I wanted, and lucked out on a foreclosure

Now the house was well designed to age in place, but the pool was nothing like your gorgeous pic! Its a standard grecian vinyl package that was installed in a former storm water catch basin...a "cheaper pool," but there had been expensive engineering to manage the water table issues via sump and drainage plus a big investment in creating a terrace on the hill to slow down runoff.
No fountain? Okay...I bought an outdoor fiberglass fountain and ran a mandeville trellis around it. No firepit? Bought a portable propane one. No outdoor kitchen? Made a kitchen in the small polebarn that now serves as a pool house. Got myself an outdoor bar, couch, awning, swing, plantings instead.
Perhaps a poor-man's paradise ... compared with your drawing...but my quality of life, social times, and health have improved dramatically!
Some day I will cap the cement with slate for the ultimate look I want but in the mean time I'm just enjoying having the water! Each year of the last four I add a new "feature" to my pool area with cash on hand.
Today, you can do a lot to dress up a vinyl pool, and save 10s of thousands going that route. You can do vinyl in irregular shapes, cap with flagstone, etc. For a water fall, knowing what I now now about pool chemistry and ph, I wouldn't install one in a new build...but would create the fountain feature separately and isolated from the pool water. Same with a spa.
SO, take a look at vinyl options...the money you save can be spent on some beautiful natural stone surrounding, and your pool area can evolve over time

Life's too short to go without, IMHO!
I hope you get some options priced that are more in your comfort zone. I feel you should be able to knock about 30% off that price if you do. Best wishes!
